Calculations for pump sizing

Power consumption pump shaft, power requirement motor, power consumption, diesel consumption)

Required information for calculating the pressure head H in mH2O

Determination of the vertical height from the water level to the inlet of the pump in m

mH2O

Friction losses in the suction line with foot valve, manifold etc. in mH2O

mH2O

Determination of the vertical terrain height from the place of installation of the pump to the highest terrain point in m

mH2O

Friction losses in the pressure line according to the friction loss curve for ground pipes in mH2O

mH2O

Nozzle operating pressure of the sprinkler used in mH2O / required inlet pressure at the rain machine in mH2O / required inlet pressure at the pivot in mH2O

mH2O

Note: 1 bar = 10 mH2O

Alternatively,

you can enter the required pressure of the pump in bar here

Required information to calculate the power requirement at the pump shaft

Output in m³/h

m³/h

Efficiency of the pump in %

Information on the calculation of the power consumption of the electric motor pump

This information is required if you are working with an electric motor
instead of a diesel engine and want to determine the current consumption.
